You don't understand how hard a loud crowd makes it unless you've done it yourself. I'd be a liar if I said that people don't sneak a peek, but that is NORMALLY just to know when to be ready for "stick!". The person passing can more easily judge where they are and the speed they're running. Also, if you sneak too much of a peek and you step on the inside of the curve receiving, that's an automatic DQ. There are some things I would not have done as a coach:
--Having Jeneba pass or Allyson, when Allyson is much more experienced and Jeneba is shorter.
--Sticking your hand back instead of down, once again with a shorter athlete passing.
But, when you run the 4X100 at Mt. Sac, there are ~10000 fans but the noise is really in the home stretch. Allyson ran leg 2 and passed to Jeneba running leg 3, so this was really minimum noise at Mt. Sac. They got to Nassau and the noise was MUCH louder and they were much closer to it. I suspect they had to improvise and that's what caused the fail (along with going for the WR).
